It is not too useful to make bold unsupported claims that the current administration has the power to subvert elections. That just lowers us to their level, and the last thing we need is for a further erosion in confidence in our democratic system. The states run elections, and no matter what Trump says to get people to keep paying attention to him, they don't jump when the president tells them to. The feds have money and nukes, but States have a lot of the actual power.
